JAIL-noon LOCK Ann ornnnrrne lrncnnnrsn Application filed November 6,1909. Serial No. 526,526..

To all whom it may concern:

Be it known 'thatI, FOLGER ADAM, a citizen of the United States,residing at J oliet. in the county of Will and State of Illinois, haveinvented a -new and useful Improvement in Jail Door Locks and OperatingMechanism,

of which the following. is a specification.

This invention relates to improvements in gang locks for sliding celldoors and has for one of its objects the provision of a gang lock,adapted when thrown in one of its ,positions, to permit the simultaneouslocking of all of the closed doors of a row of cells and When thrown inanother position to unlock the same;

A further object of the invention consists in'the provislon of a ganglock constructed and arranged so that-when it is unlocked in one ofits'positions all of the doors of the row of cells will be locked,

but may be independently unlocked by separate door locking devlces, withwhich each dooris provided, and which locking devices are operativelyconnected with the gang look. In the most improved embodiment of myinvention the separate locking devices for each door are normallyengaged therewith to lock the same and when the doors are unlocked bythe gang lock the separate door locking devices are operated by the ganglook. I

A further object of this invention is to provideveach of the separate"door locking devices with means for dead locking any one or more of thedoors whereby such doors cannot be opened by the gang lock, or bythedoor locking mechanism proper, the arrangement being such that thedead look-- ing of one or more doors does not in any way interfere withthe simultaneous locking or unlocking of the remaining doors by the vgang lock.

The invention also contemplates a gang operating device or mechanism forthe doors arranged and designed to open and close all of the doors inunison, the feature of novelty, of which consists, in the operativeconnection of'the gang operating device with the gang lock, and separatelocking devices, so that all of the doors which are under control of thegang lock will be throwninto operative relation with the gang operatingdevice to be opened simultaneously and so that those doors which are fdead locked f or those. doors which are not in operative adjustment withthe gang lock, and are in adjustment to be opened only by the separatelocking devices, may be opened or closed and locked wholly independentlyof the gang operating device.

Patented Nov. 5,1912.

The invention includes other features 'of novelty and details ofconstruction which willbe more fully described in connection with theaccompanying drawings and which will be more particularly pointed outand ascertained in and by the appended claims.

In the drawings: Figure 1 is a front elevation of one end of a tiershowing one comnlete cell and a portion ofan adjoining cell with partsbroken away to show the operative mechanism. Fig. 2 is a similar viewofa portion of the structure shown in" Fig. 1 on an enlarged scale; Fig.3 isan end elevation of the structure Shown in Fig. 2 looking in thedirection of the arrow 3 thereof. Fig. 4 is a fragmentary sectional viewof the gang lock and one door lock showing the gang lock in a finallocking position wherein all. of the doors' are 'locked and wherein noneof the doors can beopened or unlocked by theirrespective door locks.Fig. 5' is a similar view with the gang lock in an intervening position.and with all of the doors of the cells locked but in. an adjustmentwherein any one of the' cell doors can be unlocked by operation of theirrespective door locks. Fig. 6 is a similarview with the gang lock in anunlhcking position showing an adjustment wherein all of the doors'areunlocked and may be simultaneousl'y opened by the gang operatingmechanism. Fig. 7 is a similar view illustrating the gang lock in afinal position and one door lock in a dead locking position in whichposition its respective door is locked and will remain lockedirrespective of the position ofthe gang lock. being impossible to unlockthe door from the lock proper and only possible to unlock the door byreadjustment of the dead locking means. a view similar to Fig. 2 showingthe door opened by the gang operating device. Fig. 9 is a detached planview of a portion of the gang operating device. Fig. 10 is a view inelevation of a door locking bar. Fig.

Fig. 13 is aview of one of the gang locking bars showing the same in its difierentoperating positions. Fig. 14 is a view similar to Fig. 5 with thelocking mechanism in a position to permit the jail door to be opened.Figs. 15, 16 and 17 are enlarged detail views of the individual lockingmechanism.

Like numerals of reference designate similar parts throughout thedifferent figures of the drawings.

Referring specifically to the construction shown, 1, designates doorsmounted upon rollers 2, adapted to run upon a suitably formed railortrack 3, to afiord requisite sliding movement of the door abreast of thedoor way. The door is provided with a locking member which is preferablyin the form of a rigid notched member 4 having notches 5 and 6. Aboveand below the members 4, each doorjs provided with notched lugs 7,preferably rigidly secured to the doors, the notches 8 thereof being invertical alinement with the notches 6 of the members 4. Each door isprovided with an independent lock indicated as a whole at 9, and withwhich the member 4 of the respective door cooperates. An -abutment orjamb strip 10 is disposed on one side of each doorway to receive theimpact of the doors when closing and said strips are provided withsuitable notches 11 and 12 for permitting passage of the member 4 andlugs 7, respectively.

Lying back of each jamb" strip 10, or on that side opposite to the sideagainst which the door engages, are two locking bars, one of which isdirectly connected with and forms a part of the gang lock, and the otherof which is connected with the first mentioned bar indirectly preferablythrough the door locks, and which may be operated by the gang lock, orthe door lock, or which may not be operated byeither when the door lockis in a deadlocking position. One of said bars being adapted to act onan individual door lock when thrown out of operative relation with thegang lock.

The gang locking bars are indicated at 13 and are provided with engagingportions preferably in the form of elongated slots 14 and 15, the slots14 being adapted for engagement with the notches 6 of the members 4 andthe slots 15 being adapted for engagement withthe notches 8 of the lugs7. The bars 13 are operatively connected with a gang shaft 16,conveniently arranged above each tier of doors and extending throughoutthe length thereof.

The operative connection between the bars 13 and the shaft 16 mayconsist of eccentrics 17, rigidly secured to the shaft 16,

and eccentric straps 18 suitably secured, or

if desired formed integral, with the bars 13. The gang shaft 16 may bepolygonal in cross section to facilitate non-rotative engagement of theeccentrics thereto, as clearly shown in Fig. 13.

A device is provided for operating the gang shaft 16 and, as shown, saiddevice,

consists of a lever 19, pivotally mounted at 20, upona notched quadrant21, secured in any desirable manner to the structure. Said lever isprovided with a common form of manually operable sliding dog 22, adaptedfor engagement with notches 23, 24 and 25 of the quadrant 21 to lock thelever 19 in three different positions of adjustment. The

lever19 is provided with a pin 26 having 'slidin engagement with aslotted projection 2 of a rack bar 28, which is mounted to bereciprocated vertically in a lower guide 29 and an upper guide 30. I Arack 31 is provided on the upper end of said bar 28 and engages thepinion 32 on the gang shaft 16. It will be obvious from the foregoingthat as the lever 19 is shifted,"from' one position to the other,movement will be imparted to the gang shaft 16 and to the gang lockingbars 13 to adjust the latter to desired positions.

The locking bars 33 lie abreast of and in abutting relation with thegang locking bars 13 and are provided with engaging portions preferablyin the form of slots 34 and 35, slots 34 engaging the notched portion 6ofthe locking members 4 and slots 35 engaging the notches 8 of the lugs7.

The construction of the independent door locks will next be described indetail.

Each lock includes a casing 36 provided with a bolt guiding pin 37 and aguiding socket 38 arranged in vertically alined relation. A bolt 39 isapertured at 40 to receive the pin 37 and .is provided with a shank 41disposed in the socket 38. A bolt spring 42 is interposed between theupper ends of the same and a shoulder 43, formed in the easing, tonormally hold the bolt 39 in the posi; tion shown in Fig. 4. The lowerend of the bolt39 is recessed at 44 to permit the end of the member 4 toproject therein and the bolt is provided with a latch member 45 adaptedfor engagement with the notch 5. The front face 46 of they latch portion45 presents an inclined face to the end of the in mber 4 so tl at whenthe member 4 is thin t into the position shown in Fig. 4. the bolt39-will be automatically raised and subsequently lowered, by the spring,into engagement with the member 4. A key post 47 is revolubly mounted inthe casing 36 and is provided with a slotted portion 48 to receive asuitably formed key. The lower end of the key post is provided with alug 49 adapted for v engagement with a bolt actuating plate slidablymounted in the casing 36. As- Shown the bolt actuating plate 50 isslottedla't 51,

and a pin 52, mounted on casing 36, projects therethrough to guide thelower end of said plate. The upper end of said pla te'slides between twolugs 53. The plate 50 is provided with an extension 54 engaging a lug 55which serves toraise the bolt 39 when the plate 56 are pivotally mountedonthe stationary pin 52 and said wards project into a suitable recess inthe key the key and mounting 52, r

formed'notches 58 provided with shoulders 59, in the wards 56. Thisengagement of the wards 56 with the post 57, which is normallymaintained by the spring 60, renders impossible the upward or downwardmove ment of the plate 50by any but the properly formed key. When theproper key-is applied to the lock thewards 56. are freed from the post57 and the plate 50 is free to beoperated by the lug 49 against the lug55 to raise the same and the bolt 39 0f whichit is" apart. When the bolt39 is free from gang and deadlock control, as shown in Fig. 7, theupward movement of the plate 50 is adapted to raise the bolt 39 to theposition shown in Fig. 6, against the pressure of the spring 43, whichspring also serves to return the bolt 39 and the plate 50, upon'therelease of pressure on the key, to their original position as shown inFig. 4, Where any further downward movement ofthe plate 50 is preventedby the top of the slot 51 coming. to rest upon the pin 52 which, as'hasbeen staltged, is integral with the casing 36 of the loc The partshereinbefore described constitute what will hereinafter be termed thedoor lock proper and the ,function of the same is to permit theattendant to unlock any one of the cell doors which may be thrown out ofrelation wit the gang-lock.

The relation which th lock mechanism proper has with the gang'lock willnext be described in detail;

A projection 60, carried by the bolt 39,

has operative connection with the gang look mg bars 13, and the lockingbars 33, and

performs the further function of operatively connecting said bars witheach other. As

shown, said projection 60 is in the form of a rod which engages anaperture 61 in the locking bar 33, and aslot 62 in the gang locking bar13.. It will he noted that the slots 15 are of greater length than theslots 35, and that the slots 14 are'of greater length than the slots 34,and that the slot 62 is sufiiciently elongated with respect to theaperture 61 to correspond with the -extra length of the slots 14 and 15.The extra play afforded the gang locking bars 13 permits the 50 isactuated. A .plurality of Wards post 47 to be' engaged shifted upontheir pivotal ward post 57 is mounted. ,upon the plate 50 and engagessuitably tion or rod, 60. Wh

same to be raised out of locking "relation .with the members 4 and thelugs 7 whenthe S wung from the notch 23 to thenotch'24, which istheposition shown in Fig. 5, without releasing the locking bars 33 fromtheunembers 4 or lugs 7. This is the neutral or intermediate position oradjust, ment of the gang lock which does not unlock permits any one ormore In this position each bar 33:may be, con 'sidered an independent.door lock with means, which may be the door lock,-for actuating thebarto unlock the door. It Will be readily understood that in the positionshown in Fig. 5 the raising of. a bolt 39, by a key, will also serve toraiseajcorrespondlng bar 3.3 and'releasethevlugs' 7 therefrom; as

well as the correspondin member .4 there from, the bolt 39 acting ttrough the rojecen the gang ock is thrown from'alock-ingto an unlockingposition to unlock all of the doors simultaneously, then the lever 19 isthrown from the notch 23 to the. notch 25, carrying all of the bars 13asufiicient distance u disengage said bars from t members!and'subsequent-ly act through engagement of the lower ends of the slot-62, W1 11 the projectionGO, to carry the bars 33 up rdly a suflicientdistance to disengage the same rom the members 4 and lugs 7, which movemntfwill .also carry the bolts 39 up? wardly a suflicient distance todisengage thelatch members 45 from the members 4. 7 It will thus be seenthat when the gang lock is thrown intoan unlocking position both bars 33and 13 form a part of the gang lock and 1" that said bars areoperatively connected with each other, and with the independent l0ckingdevices proper. It will be further noted that the projection 60constitutes means performing a distinct function of operativelyconnecting the bars 13 and 33 with each other and a separate distinctfunction of operatively connecting the independent locking devicesproperwith the gang lock,

It is sometimes desirable to dead lock one or. more of the doors of arow of cells so that it cannot be opened by the gang lock, or by thelock proper, and this feature of the invention will now be described indetail.

As shown the dead lock. device comprises a key post 63 having a key slot64 and a lug 65. A ward plate 66 is slotted to receive a stationary pin67 and is guided between 1ugs 6 8 when actuated by the key. A

gang locking mechai wardly to first e lugs 7 and actuated by a properlyplurality of wards 69 are pivotally mounted 69. Springs 73 normally holdthe wards 69' in engagement with the post 70. Whenthe plate 66 is inthe'pos'ition shown in Fig. 4

one end of the slot in'the plate-66 'isf inengagement with the pin 67and the shoulders with the post 70. and

7 2 are in engagement theplate 66 is thereby held in the position shown.In retracting the plate 66, from the position shown 'in Fig. 4:,totheposition shown in Fig. jlocking or preventing action of the lockproper when the dead lock is in an active shown in Fig. 7, the key post63 is turned to the left and the post 70 is brought into engagement withthe notches 71 thereby holding the plate 66 in'a retracted position. Theprojection or rod 60 is preferably slidably mounted in the bolt 39 andis provided -with an elongated loopextension 74 which engages a lug 75on the plate 66. It will be.

noted that this looped eXtension74 provides a lost motlon connectionbetween the dead lock and the lock proper permitting the lock proper ;tobe freely operated in any mannerwithin th e limits of its action whenthe deadlockiis in a neutral position, as 4. Means are provided forposition '(Fig'. 7) and as illustrated, said means includes a lug 76preferably disposed upon'the outer or front wall of the lock casing 36and positioned thereon in such a manher as to. permit the loop 74 toreciprocate freely on the right hand side of the lug 7 6 when the deadlock is in a neutral position. It will'be further noted that this lug76' prevents the dead look from being ,thrown, from a neutral to anactive position, except when. the bolt 39 and loop 74 are in a lowermostposition, see Fig. 6, in

view of the fact that the loop 74 would engage the lug76, laterally, andprevent the plate 66 from being thrown into a retracted position. Itwill also be noted that when the bolt 39 is in a lowermost ;position, asshown in Fig. 7, and the dead lock is thrown from 'a neutral to anactive position, the loop 74 is shifted abreast of the lower end of thelug 76 so that the bolt 39 cannot be raised by either thekey of thelockproper .As' a further means of preventing the gang look fromoperating the lock proper when the dead lock is in an active positionthe rod or movement of the plate 66 to throw the dead look from aneutral to an active position will withdraw said projection 60' fromengagement with the slot 62, therebv disconnecting the bars 13 and 33from each projection 60' is of such length that the laterally shiftingother and preventing any movement of the bar 33 of the dead locked doorunder the action of the gang look. It will thus be seen that when thedoor is dead locked it is secured-by its bolt 39 and bar 33 engaging themember 4 and also by the bar 33 engaging both'of the lugs ,7 therebysecurely holding the door locked.

"Reference will next be made to a gang door operating device the novelfeatures ofwhich consist in its operative'connection with the lockingmechanisms.

As shown, a gang operating bar 76 extends throughout the length of a rowof cells and is preferably disposed above the doors thereof. Any formof-suit-able bearings may be provided for the bar 7 6 to permit oflongitudinal shifting movement thereof. The bar 76, as shown, isoperated at one end of a row of cells by a device which may comprisethefollowing elements: A link 77 is pivotally connected to the bar 76', at78', and at its opposite end said link 77 is connecte with a lever 78,at 79, and said lever 78 is pivotally mounted at 80, to a suitablebracket 81, secured-to the structure in "any desirable manner; The lowerend of the lever 78 is slotted at 82 and is connected with a manuallyoperable lever 83, which is pivotallymounted at 84', to a bracket 85,and is connected with the lever 78, at 86, the

:slot 82 affording requisite movement of the connection 86 when thelever is shifting from the position shown in Fig. 2, to the positionshown in Fig. 8, and vice versa, as will be obvious from the drawing. Inthe form shown, each door is connected at 87, with one end of a lazytongstructure 8 8, the other end of which is connected at 89 with anydesirable stationary part, as 90.

Intermediate of its ends the lazytong structure 88 is connected at 91with a member 92, which is in the form of an arm, and which is designedto be normally out of operative connection with'the gang operatingdevice, when the doors are locked, either by the door looks or ganglocks, all of said bars being adapted to be simultaneously thrown intooperative relation with the gang operating-device when all the doors areunlocked, by the gang lock, or as many of the doors as may be unlockedby the gang lock. The members 92 of those doors which are not unlockedby the gang lock, or which may be dead locked are not thrown intooperative relation'with the gang operating device. Furthermore after acertain number of doors have been unlocked by the gang lock and openedby the gang operating device those doors remaining closed may besubsequently opened by unlocking the independent locks and the lockingbars 33 of such door or doors will not interfere with the gang operatingmechanism. Referring to the specific construction shown, each member 92is connected with a locking bar 33, at 93, a suitable slotted flportion94 ment of any one of the members 92 ofthose doors not under control ofthe gang operating device and not opened by the gang lock and which aresubsequently opened after the doors,. under .control of the gangoperating gang lock devices, have been opened, it being noted that atsuch time the studs 95 will have been shifted to the right before thedead lock or subsequently opened doors have been opened, therebyshifting the studs into the position shown in dotted lines in Fig. 9. Itwill be noted that a door will only be thrown into operativerelationwith the gang operating device when its respective bar 33 has beenshifted upwardly throughout its extreme unlocking position so as'tobring the notch 94 into engagement with the stud 95. When the gang lockis adjusted to. a neutral position, as shown in Fig. 5, the bars 33 willnot have been moved and the doors will not be thrown'into operativerelation with the gang operating device. When however the gang lock hasbeen thrown into an unlocking position, as shown in Fig. 6, all of, thebars 33, under control of the gang lock, will be shifted upwardly asufficient distance to engage the members 92 with the studs 95..Assuming that the gang lock is in a neutral position, as shown in Fig.5, with all of the doors closedand with the gang operat-' ing device ina closing position, as shown in Fig. 2, any one of the doors may beopened by its individual look without throwing such v door in operativerelation with the gang dein the position vice. To afford this advantagethe parts are so proportioned, and the upper portions of the notches 5and 6 of the member 4, and the notches 8 of the lugs 7, are reduced inheightso that the lugs 7 and member 4 of the door to be opened may bereleased from engagement with the bar 33 and the. bolt 39without'raising either a distance equal to the distance to whichthey'are raised when operated by the gang lock. With the parts set forthin the foregoing, a key may be inserted in the key post 47 of the doorto be opened and the bolt 39 and bar 33 will be raised asuflicient-distance to clear the upper reduced tops of the notches tofree the member 4 and lugs 7 butthis upward movement of the bar 33 willnot be son of the fact that of the row have sufficient to engage thenotch 94 with the pin 95, see Fig. 2, therefore the attendant can slidethe door free to trol. l

1 While the operation of my invention will be clear from the foregoingan understanding thereof may be facilitated by a short recapitulation.

- With the lever 19 in the final locking position, as shown in Fi 4 allof the bars 33 and 13 will be in-loc ing engagement with the lockingmembers and lugs of all the doors and all of open-independently of thegang conby their individual locks proper, namely the bolts '39. In thisposition all of the members 92 will be out'of connection with the gangbar 76, and it will be absolutely impossible to unlock any of the doorsby the individual door locks because the gang lock will hold the bars 13in a full locking position thereby preventing the pins and bolts 39 frombeing raised. tion, however, nothing will prevent any one of the doorsfrom being dead locked because the loop 74 are below the lugs 76 and thedead locking device can be readily turned to withdraw the pin 60 fromengagement with the slot 62, thereby throwing such individual lock outof relation with the ang lock and preventing the bolt 39 from eingoperated by the key post, 47, by reathe loop 74 is beneath the lug 76.It will thus be seen that if it is secretly decided at a late hour toprevent the release of a prisoner in a certain cell on the followingmorning said cell can be dead locked after all of the other cells beenfinally locked and that when all of the other cells have subsequentlybeen unlocked by the gang lock the dead locked cell will still remaindead locked. If it should be'desired to open any one of the doors of arow of cells and maintain all of the other doors of the cells of thisrow locked then the lever 19will be thrown into a neutral position withthe gagement with the'slot 24'; This movement rotates the gang shaft 16and lifts all of the bars 13 out of locking engagement with the members4 and lugs 7 of all the doors thereby temporarily throwing all of thedoors out of control of the gang lock. From Fig. 5'it will be seen thatthis neutral position does not lift the bars 33, and does not liftthe-bolts 39, therefore all of the doors are individually locked b thebolts 39 and bars 33. By inserting a ey in the post 47, of the doordesired to be 39 and bar 33 may be lifted a suflicientdistance to freethe member 4 and lugs 7 and permitthe .door tobe opened. As, hereinbefore described this movement will not be suflicient to cause the bar33 to'engage the open and the door will be,

the locking members of allot the doors will be additionally locked Inthis posidog 22 in em opened, the bolt member 92 with stud 95. It willalso be noted that when the gang lockis ina neutral positionnone of thebolts 39 are raised,

therefore any one of the doors of the cells may be deadlocked.Ifitis-de'sired to unlock all of the doors of a row of cells by the ganglock the lever 19 will be raised to the unlocking position shown in Fig.6'

with the dog 22 of thelever 19 engaging the notch 25, in which position,the lower ends ofthe slots 62 will engage the rods 60 and raise all ofthe bars 33 and bolts 39, except for such doors as'have been deadlocked.

by withdrawing their respective pin or pins 60 from engagement with theslot 62. This movement imparted to the bars 33 will be greaterthan themovement imparted thereto when doors 'are unlocked separately and willbe sufficiently great to engage all of the notches 94 in the members 92with the studs ;95 and place all of the doors, not dead locked, intooperative relation with the gang operating device. By now throwing thegang operating'lever 83 from the position shown 1n ,Fig. 2-to theposition shown in Fig. 8 all of the doors, connected with the gangoperatingdevice may be simultaneously opened and subsequentlysimultaneo'usly closed.
